Gauge Coupling Unification in Gauge-Higgs GUT: Theory and Phenomenology
Andrei Angelescu, Andreas Bally, Florian Goertz +1
We present a concise survey of the running of gauge couplings in realistic models of gauge-Higgs grand unification in a slice of AdS space and investigate their potential unifi…
Restoring Naturalness via Conjugate Fermions
Andrei Angelescu, Andreas Bally, Florian Goertz +1
We propose a novel mechanism for cancelling the leading order contribution to the potential in composite Higgs scenarios. The mechanism relies on the splitting of a real representa…
SU(6) Gauge-Higgs Grand Unification: Minimal Viable Models and Flavor
Andrei Angelescu, Andreas Bally, Florian Goertz +1
Gauge-Higgs grand unification theories are models of gauge-Higgs unification that extend the electroweak group into a simple group that includes the color symmetry. The minimal opt…
Non-Restoration and Composite Higgs: Singlet-Assisted Baryogenesis w/o Topological Defects
Andrei Angelescu, Florian Goertz, Aika Tada
Simple scalar-singlet extensions of the Standard Model with a (spontaneously broken) symmetry allow for a strong first order electroweak phase transition, as sought in order…
Unification of Gauge Symmetries... including their breaking
Andrei Angelescu, Andreas Bally, Simone Blasi +1
In this talk, we present a minimal viable scenario that unifies the gauge symmetries of the Standard Model (SM) and their breaking sector. Our Gauge-Higgs Grand Unification setup e…
On the single leptoquark solutions to the -physics anomalies
Andrei Angelescu, Damir Bečirević, Darius A. Faroughy +2
We revisit the possibilities of accommodating the experimental indications of the lepton flavor universality violation in -hadron decays in the minimal scenarios in which the St…
Minimal SU(6) Gauge-Higgs Grand Unification
Andrei Angelescu, Andreas Bally, Simone Blasi +1
We present a minimal viable Gauge-Higgs Grand Unification scenario in warped space based on a bulk symmetry - unifying the gauge symmetries of the SM and their breaking sec…
Integrating Out New Fermions at One Loop
Andrei Angelescu, Peisi Huang
We present the fermionic universal one--loop effective action obtained by integrating out heavy vector--like fermions at one loop using functional techniques. Even though previous…
Lepton Flavor Violation and Dilepton Tails at the LHC
Andrei Angelescu, Darius A. Faroughy, Olcyr Sumensari
Starting from a general effective Lagrangian for lepton flavor violation (LFV) in quark-lepton transitions, we derive constraints on the effective coefficients from the high-mass t…
Beyond brane-Higgs regularisation: clarifying the method and model
Andrei Angelescu, Ruifeng Leng, Grégory Moreau +1
The class of higher-dimensional scenarios, based on a brane-localised Higgs boson coupled to bulk fermions, can address both the flavour puzzle and gauge hierarchy problem. A key q…
Single Leptoquark Solutions to the -physics Anomalies
Andrei Angelescu
We examine various scenarios in which the Standard Model is extended by a light leptoquark state to explain one or both -physics anomalies. Combining low-energy constraints and…
Multistep Strongly First Order Phase Transitions from New Fermions at the TeV Scale
Andrei Angelescu, Peisi Huang
In spite of the vast literature on the subject of first order Electroweak Phase Transitions (EWPTs), which can provide the necessary conditions for generating the Baryon Asymmetry…
Closing the window on single leptoquark solutions to the -physics anomalies
Andrei Angelescu, Damir Bečirević, Darius A. Faroughy +1
We examine various scenarios in which the Standard Model is extended by a light leptoquark state to solve for one or both -physics anomalies, viz. $R_{D^{(\ast)}}^\mathrm{exp}>…
Les Houches 2017: Physics at TeV Colliders New Physics Working Group Report
G. Brooijmans, M. Dolan, S. Gori +80
We present the activities of the `New Physics' working group for the `Physics at TeV Colliders' workshop (Les Houches, France, 5--23 June, 2017). Our report includes new physics st…
Scalar Production in Association with a Z Boson at LHC and ILC: the Mixed BEH-Radion Case of Warped Models
Andrei Angelescu
The radion scalar field might be the lightest new particle predicted by extra-dimensional extensions of the Standard Model, thus possibly leading to the first signatures of new phy…

Dark Matter Phenomenology of SM and Enlarged Higgs Sectors Extended with Vector Like Leptons
Andrei Angelescu, Giorgio Arcadi
We will investigate the scenario in which the Standard Model (SM) Higgs sector and its 2-doublet extension (called the Two Higgs Doublet Model or 2HDM) are the "portal" for the int…
Scenarii for interpretations of the LHC diphoton excess: two Higgs doublets and vector-like quarks and leptons
Andrei Angelescu, Abdelhak Djouadi, Grégory Moreau
An evidence for a diphoton resonance at a mass of 750 GeV has been observed in the data collected at the LHC run at a center of mass energy of 13 TeV. We explore several interpreta…
Diboson resonances within a custodially protected warped extra-dimensional scenario
